Standardized Testing for North American Building Schedules

Every certificate held by Guangdong Dejiyoupin Doors and Windows Co., Ltd. represents empirical testing in accredited third-party laboratories. Review our core credential categories below.

North America & Global Standard

AS 2047 & Hurricane Wind Resistance

Certified to AS 2047 N6—the highest rating for extreme wind pressures, cyclonic events, and air-water penetration resistance. Ideal for coastal zones in the United States and severe storm areas.

  • Tested under dynamic wind conditions
  • Zero water infiltration at designated pressures
  • Robust structural deflection tolerance
Energy & Thermal Compliance

NFRC & Energy Star Compatibility

Our thermally broken aluminum systems and insulated Low-E double or triple glazing packages meet rigorous U-factor and Solar Heat Gain Coefficient (SHGC) targets, vital for Canadian winters and northern U.S. climates.

  • Low U-factor thermal insulation
  • Argon gas infill & warm-edge spacers
  • Prevents condensation and interior cold transfer
Life Safety & Fire Protection

UL Fire-Rated Door Assemblies

For commercial lobbies, multi-family entries, and mixed-use complexes requiring designated fire separations. Engineered with fire-resistant cores, intumescent seals, and approved hardware systems.

  • UL 10C / NFPA 252 testing protocol matching
  • Commercial pivot and side-hung configurations
  • Factory documentation provided for building inspectors
Quality Management

ISO 9001:2015 Production Base

Guangdong Dejiyoupin Doors and Windows Co., Ltd. operates an ISO 9001-certified 180,000 m² manufacturing campus. In-house processing covers CNC milling, powder-coating, manual patina, and rigorous final staging inspections.

  • Batch traceability on all aluminum alloys
  • Strict millimeter-accurate tolerance checks
  • Export wood-crate packing protocols
Proprietary Technology

Patented Four-Side Six-Point Security

North American homeowners and project owners prioritize physical security. Our patented locking system engages multipoint hardened steel bolts across all door leaf peripheries to resist forced entry.

  • Anti-pry perimeter interlocking points
  • Compatible with smart biometric/RFID systems
  • Patented exclusively by Guangdong Dejiyoupin
European Conformity

CE & International Standards

Certified in compliance with EU Construction Products Regulation (CPR). Demonstrates non-toxic coatings, acoustic damping values, impact resistance, and dependable long-term mechanical cycling.
